Lobby Control Units 1, 2 and 3 can make simultaneous calls as long as a line is not
in use by another Lobby Control Unit. For example, if Lobby Control Unit 1 uses
line1, Lobby Control Unit 2 can use Line 2 and Lobby Control Unit 3 can use
line 3.
When Lobby Control Unit 1 is using line 1 and Lobby Control Unit 2 also wants
to use line1, which is busy, then a line busy message displays on Lobby Control
Unit 2.
